At the moment the most productive common standard of SD and microSD memory cards is an Ultra High Speed Class 3 (UHS-I (U3)) standard, which provides a minimum write speed of 30 MB/s and designed to support video recording in format 4K Ultra HD. Of course, not all users have a need for such speeds. Many may use more reasonable version of the standard UHS-I Speed Class 1 (U1) with a write speed of at least 10 MB/s. And this class includes a model Transcend SDHC USH-I Premium 200x (TS32GSDHC10).

Tested novelty is available in six different capacity modifications, two of which are in format SDXC for 64 and 128 GB. Another interesting detail is the fact that on page and on the package the manufacturer claims only the maximum data rate, rather than read and write.

Design and package

The memory card supplied in the traditional format of the device disposable blister pack, which allows to evaluate the appearance of new items before buying. On the front side it is an indication of the manufacturer, model storage, memory capacity and maximum data transfer rate (30 MB / s).

Model Transcend SDHC USH-I Premium 200x is made of blue plastic. Its dimensions are absolutely standard and fully comply with the format of SD (32 x 24 x 2,1 mm). The front side of the device contains name of the device, its scope, and speed characteristics. On the reverse side you can find the interface contacts and safety switch which limits the ability to record information.

File system

By default, the memory card is formatted in FAT32, which is characterized by restrictions on the maximum size of the file (4GB).

After formatting to the file system NTFS, 95 MB are reserved for its needs and the available space is slightly smaller. However, in connection with the above restriction in the file system FAT32, for the device of 32 GB it is more logical to use NTFS or exFAT.

Testing

The following test bench was used for testing Transcend SDHC USH-I Premium 200x:

During the testing the storage device showed the following results: read speed in many benchmarks exceeded the stated rate of 30 MB/s and reached 44 MB/s and write speed was at the level of 22 MB/s. That's enough to quickly save even the bulk material.

As for the comparison with competitors, the novelty showed similar performance with Transcend microSDHC Class 10 Premium, which is not surprising, since they are both neighbors of the lineup. In general, the hero of our review shows good speed for everyday use, so it is perfect for use in photographic and video equipment, not focused on the video recording in the resolution of 4K Ultra HD.
